Specification of Letters Patent.

Application filed March 28,- 1910. Serial No. 551.880.

To all whom it may concern:

Be it known that l, HENRY L. S'lAUFI-ltlt, a citizen of the United States. residing at Lansdale; in the county of Montgomery, State of Pennsylvania, have invented certain'new and useful Improvements in Pipe Vise Posts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as wiltenable others skilled in the art to which it appertains to make and use the same.

This invention relates to supports for steamfitters pipe rises, and has for an object to provide an extensible post which may readily be set up indoors or outdoors and will prevent the vise from vibrating when in operation.

A further object is to provide a device of this character which will secure the vise at any desired height from the floor.

Hitherto it has been customary for plumbers to procure an ordinary wooden .post and after cutting the same to reach from the floor to the joist of the cellar in which they were working, to lose a great deal of time erecting the post and giving it the firmness necessary to hold the pipe vise when cutting a thread on the pipe. ThlS invention provides a metal post which can be adjusted to reach from the floor to the joist without loss of time.

In the accompanying drawing forming part of this sp'ecificatiom'Figure 1 is a perspective yiew of the device applied. Fig. 2 is a longitudinal section view through the device. Fig. 3 is a cross section taken on the line 33, Fig. 2.

i The reference character 10 designates a metal pipe having at one end external screw threads 11 which engage the internal screw threads of a flange 12, this flange being provided with suitable openings to receive screws 13 the lower ends 01 which project beyond the bottom face of the flange 12 and penetrate the floor upon which the flange rests. The opposite end of the pipe 10 is provided with a peripheral flange 14 the purpose of which will presently appear.

Loosely fitted in the pipe 10 is a pipe 15 of less diameter than the pipe 10 and provided with external screw threads 16 which extend from one end of the pipe to within a short distance of the opposite end of the pipe as shown. A flange 17 similar in construction to the beforementioned flangeilQ is threaded upon the upper end of the pipe -15 and is adapted to bear with its fiat face upon the ceiling joist 18.

A collar 19 is provided in its bottom face with a circular rabbet 20 of sufilcienflsize to loosely receive the before-mentioned tlange, 14 of the pipe 10 and'isprovided with a threaded opening 21 which leads through this-rabbct to the top face of the" collar and receives the externally threaded p1pe. The collar 19 15 provided with radial openings through which set screws 22 arcin- Iatented Feb. 25, 1 1a cal sci-ted the terminals of these set screws'engaging the outer face of the pipe 10 and'the' bottom face of the flange 14 ofthis pipe. 'llus construction permits of the collar 19 being rotated upon the pipe 10. A red Q3 projects through the periphery of the pollar l9 and serves as a handle for rotating the collar. It is now clear that by rotatin the collar 19 the flange 17 maybe advances into engagement with the ceiling joist of 'ti room. I

Fitted on the opposite sides of the pipe 10 are a pair of blocks 24. These blocks are preferably rectangular in cross section and are provided on their inner faces with semicircular rabbets which receive the sides of the pipe. A pair of bolts '25 are passed transversely through the blocks on each side of the pipe 10 and are provided with retain-i iugnuts 26 which engage the outer face of 'oue.0f the blocks when tightened and serve to hold the blocks tightly clamped to the pipe. It is evident that these retaining nuts may be loosened and the blocks raised or lowered upon the pipe as desired. One

pair of the bolts 25 is sufiicicnt in length to extend considerably beyond the outer face of one of the blocks so that the bolts may be inserted through the bolt 0 formed in one leg of the angle llOIl base of an ordinary pipe vise 28 to secure the pi e vise to the side of the block as shown. Tiie retaining nuts 26 of the bolts 25 bear against the metal leg of the vise and thereby, mutilation of the outer face of the block is prevented. A pipe may be engaged between the, jaws of tlns pi e vise. and threaded in the usual manner, is efree end of the pipe being so ported upon a scaffolding of any preferre' form during the o oration. By adjusting the blocks 24 upon tie pipe 10 the vise may be raised or lowered upon the pipe to a position to accommodate workmen of different heights. i l

A table top 29'is swiveled upon the blocks rungs 27 'wlse rigidly secured to the top face of the fhlock and retains the swivel head of the position. The freeend of the rod of the table top, this cross brace being disposed with its ends in abutting contact with I at their upper ends .by-an annular collar 10 and provided at their lower ends with 24 and serves as" a support for the work- I mans tools. The preferred manner of connecting the table top to the blocks is as folright angles to the main and terminates in a suitable blocks. A Washer 33 is mounted on the bent portion of the rod and is bolted or otherholted or otherwise rigidly secured to a cross brace 33 secured to the bottom face a pair of parallel longitudinal braces 34 disposed upon the hottom face of the table top. F or retaining the device in operative position out of doors a tripod 35 isprovided, this tripod consisting of legs 36 connected 37 through which set screws 38 are passed to removably secure the collar to the pipe expanded portions 39 having suitable open: ings to permit pegs 40 being inserted therethrough and driven into the ground, or in lieu of the pegs screws or bolts may he em ployed as desired.

From the foregoingdescription taken in 1 neaeao connection with the accompanying drawing, it is thought the construction and operation of my invention will be easily understood, without: a more extended explanation, it being understood that various changes in the form, proportion and minor details of construction may be made within the scope of the appended claim.

What is claimed is A pipe vise post comprising a lower tubular member having an externally flanged upper end, a base for the lower end of said member, an upper tubular member externally threaded and having its lower end" freely movable in the lower tubular memher, an engaging head on the upper end of the upper member, a collar having a threaded bore engaged on the upper tubular memher and an enlargcd circular rabbet'portion ,1

in its bottom rotatably mounted on the flanged end, means torfrotating the collar to raise or lowerthe upper member and set 7 screws operating through the collar and engaging the lower tubular member beneath the flange to hold the collar against displace
